I SPECIFICATION forming part of Letters Patent No. 503,249, dated August15, 1893.

Application filed May 7, 1892. Renewed July 13, 1893- Serial No.480,423. (No model-l To aZZ whom it may concern.-

Be it known that I, ARTHUR OBRIEN, a citizen 0f the United States,residing at Helena, in the county of Lewis and Clarke and State ofMontana, have invented certain new and useful Improvements inWashbasins, Sinks, and the Like; and I do declare the following to be afull, clear, and exact description of the invention, such as willenableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention has reference to improvements in wash bowls or basins,sinks and the like, and has for its object to provide means forventilating the bowl and waste pipe, for utilizing the passage for theair of ventilation. to carry off the overflow, and means for securingthe bowls of wash basins to the top slab in such a manner as that thepoints of connection will be concealed.

My invention consists of the construction, relative arrangement andoperation of the parts constituting my improvements, all of which willbe hereinafter fully and clearly described and specifically claimed.

In the accompanying drawings in which like letters of reference refer tolike parts, Figure 1 represents in plan view, a wash basin with myimprovements thereon, the top being removed. Fig.2, is a verticalcentral section of the same with the top in place; Fig. 3, a detail viewof the bolt employed in connecting the bowl and top. Fig. 4, is a planview of a sink embodying my improvements, and

' Fig. 5, is a vertical central section of the same.

Referring to the drawings, the letter A denotes the bowl of the basin orsink, which is formed with the usual waste outlet at. This bowl hasformed integrally therewith a chamber b which extends a short distanceto the rear and finds an outlet in passages formed in a coupling 0.

dis an overflow passage which communicates with the chamber 1) and witha line of pipe to the drain pipe or'sewer. To the rear of this overflowis an abutment e, which is of sufficient height to direct the waterresulting from an overflow into the passage (1. The couplings has a ventfand an auxiliary over flow passage 9 which form a continuation of thechamber. In the event of the passage d, becoming clogged, or from othercauses, the overflow should rise above the height of the abutment, thewater will be carried off through the auxiliary passage, and through aseparate line of pipe to the sewer. The foul air and vapors from thewaste pipe and overflows find their way to the vent and from thence to apoint outside of the building, and a thorough ventilation isestablished.

In Figs. 1, 2 and 3 I have shown improved means for connecting the bowlof a wash basin to the top slab, in such a manner as to conceal thepoints of connection. it represents a bolt having a T head h, and adovetailed end h which latter enters a hole made therefor in the underside of the slab, and is held therein by means of solder. In the upperedge of the bowl I form a series of recesses'i, each of which conformsin size to the head of the bolt which it receives. Extending from therecess is an inverted T' shaped continuation which conforms to the shapeof the head of the bolt. The bowl and slab are placed together with theheads of the bolts in the recesses i; the bowl is then moved slightly tothe rear and the T heads enter the correspondingly shaped recesses j,and firmly lock the bowl and slab together. The construction of theseparts permits of a connection being made without exposing to view any ofthe means employed, and hence a very neat job is the result.

Referring to Figs. 4 and 5, 7c is an opening arranged directly over theoverflow passage 01 and Zis a plug for normally closing same. Byremoving the plug ready access is given to the said passage and pipe forthe purpose of cleaning same and removing obstructions therefrom.

In the construction shown in Figs. 1 and 2 the inner line of the topofthe bowl is carried back to a point in line with therear wall of theoverflow passage (1, and hence no plug is necessary. .I may howeverclose this passage by the top slab, and in such case an opening of theabutment, and an air vent above said in the latter with a closing plugmay be emauxiliary overflow communicating therewith ployed. and with thechamber, all substantially as I claim and for the purposes set forth. 5In Wash basins, sinks and the like, the com- In testimony whereof Iaifix my signature in x 5 I bination with a bowl formed with a Wasteoutpresence of two witnesses.
